mp15 sport scope - looking for good suggestions as to what kind of scope mount setup anyone has installed on these that allows the front sight to not get in the way when lookng trough the scope, any pictures, ideas would be great, pretty knew to the whole ar15 thing and still learning. thanks

IF you mean an actual scope (as opposed to a non magnifying red dot or the like), the front sight will "disappear" when viewed through the magnifying scope.

Otherwise, most red dots and holographic type sights offer mounts to co-witness , either lower third or absolute (in sync with the dot.) You sight in the red dot then adjust the sight to match the zeroed sight.

1-4 powered scopes are ideal for three gun type shooting and good all around units out to about 200 yards or so.

I bought a Vortex Strikefire with the high base for AR 15's. Gives a lower 1/3 co-witness. The Vortex SPARC comes with a base that can be set up for absolute or lower 1/3 co-witness. Both of these are built with AR users in mind.

Other red dots are not set up for AR's with front sight bases, so you may have to buy a riser to get the dot to the height that you want. Don't know anything about Eotech, ACOG or the other high end optics.
